My invention relates to an improvement 1nwe1gh1ngme'chan1sm.

The 0b]80t is to provlde simple means for regular weighing'on or weighing off as-the' case may be, and incidently to provide a' simple method for eliminatingthetareuof container in which the'actual goods to "any be weighed are held.-

mechanism in connection with the usual handvor pointenmovable by the Weight on I the scale, and a resett-abl'e .dial composed of: two disks adjustably connected togetheqone having two sets offigures thereon, one: set arranged :clock-wise and the other counter clock-wise and the other disk "having open ings-through-which'one set of the figureson' the other disk is discernible -from the face offthe dial accordingly "as *the'disks composing the dial 'areqadjustedythis adjustment ofthe dial beingprovided for weighing in arr-ordinary manner-by adding material to the scalepan or'platform or: by reversing the operation -that is to say :by removing portions ot-the-weig'hed material or articles.

In the. accompanying drawings:

A represents a scale of anydesirable' type and l is a pomter or 'handse'cured on the scalearborflin the customary manner. Any

form of pan 3 may be mounted at the t'op to "receive the articles or material to be weighed; i j l The dial is composed of twodisks 4 and 5 held togeth'er adjustablyby r-ivetsb extending through holes 7 in'the outer'disk i and throughthe arc-shaped slots -8.Iin"the disk 5.

Asaconvenient means of construction the outerdisk 4 of.the.dialxhas-aaflanged orifice .9 at the center which :receivesandzis rotatably niounted upon the fixed collar 10 was shownin (Fig; 3,"the.a'rbor; fixed collar and flanged orifice all being concentric.

The inner disk .5 *ofthe :dial isprovided with two sets of figures sat-its peripheryg-as shownfin'F-igure 5', -for exampleffrom zero to 15, one set extending around the disk clook+wise; and the other set extending counterclockwise, in-the'alternate spaces.

Theyouter disk 4: of the dial is provided with orifices 12,prefe'rably round in shape 7 and corresponding in number and spacing t J with thejnumbers in either'one of the sets This inventlon includes any suitablescale of fig ures 0n the-periphery ofthe "inner d-isk 5*shownin Fig. '5, =it being understood, however, that' this-is merelyillustrative and that it does not in anywise 1 limit me. 7

-The e Xtreme outer :peri hery of the outer disk 24 is 'provided with irack teeth :13 and a hand operating device 14 isrotatably mounted at someconvenientpointpreferably below the di'al and is providedwvith a pinion 15 as will .be explained .in the -'operation"of weighing.

'andk'3.

"The following will ive i eaame. at

the operation of:the weighinggmechanism:

If the :scale is set for weighing on and the 90 v 1 media; i5=1is moved :to'athe .ri htithus bringseveral additional objectswhile the first is still on the scale, the combineddials are revolved by the action of the adjusting device upon the peripheral teeth on the disk 4 until the zero figure is in exact alignment with p settable dial having two sets of numerals arthe hand or pointer. The next object is then placed upon the scale and the weight notedby the movement of the indicator hand. This method is continued. to the capacity of the scale as desired. Another example: In

weighing on, if it desired to eliminatethe tareof any container inwhich a'net welght is desired to be shown, the container is placedon, a .scale, and, assume, itv weighs two :pounds. The dial is then revolved until 'the zero figure is again in exact alignment with tainer and its weight determined. This.

method can be continued to the capacity of thescale. As a further example, assume that I this scale is being used to weigh cartons that are being filled with five pounds of dried beans .in each. In each case the tare of the carton istakenicare of by the adjusting de-.

vice. But 'owing'to the nature of the contents the indicator hands shows either a slight or undetermined over or under weight at the filling. This error which is not cone stant in every filling operation is diflicultto rectify in present weighing methods. 1 Such errors can beeasily compensated'for by the adjustin device by. bringing desired point on the dial in exact alignmentwith the indi-. cator hand;

vItis understood and weight indicating; numbers, and in fact many of the other. features" described and shown aremerely illustrative, but not in-.

' tended to-limit me, as itis my intentionto provide. scales with an unlimited weighing capacity,- carrying out and in extension of thisgeneral idea, andv to do which itwould'. only. be necessary to increase the capacity. of the dials in orderto'accomplish-thatend' -.I*claim: 1.
